Answer:
7(b^2 -2)(b^2 +2)
Step-by-step explanation:
Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.
v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)
The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.
Answer:
13, 22, 31
Step-by-step explanation:
a(n) = a +(n-1)d
a=4
d=9
°.° a(n) = 4 +(n–1)9
a(2) = 4 +(2–1)9
=13
a(3) = 4 +(3–1)9
=22
a(4) = 4 +(4–1)9
=31
hope this helps
a.they added the parenthesis
2. they added common numbers
3.they added -32x to the other side to isolate x
4.they added 8 to isolate x further.
5.they divided 47 by both sides to determine x
